Interstate Redux

Sometimes we at mental_floss make mistakes, or just don't get all the facts. Over at the magazine we call "˜em "mental flaws." Whelp, here now is, perhaps, our first mental flog (that would be a blogging flaw):

Yesterday I pontificated thusly: "Not sure how one can pinpoint the exact 50-year anniversary of our illustrious Interstate system, but today seems to be the day."

Insert foot in keyboard, as we skip to today where I luckily discovered this fact via The Christian Science Monitor:

"On June 29, 1956, President Eisenhower signed a bill to build the Interstate Highway System -- a dream of his since he crossed the US in 1919..."

And so that's why yesterday was the 50-year anniversary, and, more to the point, why I hang my head in shame today.
